“Well made but this either fits your seat tube or it doesn't. It's not very adaptable. Too big for my 30mm OD seat tube (ID 27.2mm) and would need a thick shim to work. I tried doubling up on shims made from a tin can and it was still too large. Couldn't switch over the lever on the current Allen key seat clamp either. 30mm clamps are simply unavailable in this country and out of stock overseas. What gives?”
